I can confirm this problem on the following platforms.
Intel NUC 8i5BEH with Ubuntu 18.04
Intel NUC 8i5BEH with Ubuntu 18.04 and the hardware enablement stack
Intel NUC 8i5BEH with Ubuntu 20.04
Intel NUC 10i7FNH with Ubuntu 18.04
Intel NUC 10i7FNH with Ubuntu 18.04 and the hardware enablement stack
Intel NUC 10i7FNH with Ubuntu 20.04
I can boot the system and after booting I can connect via SSH for a few minutes and then the connection is dropped. There is nothing on the log files on the client or the server.
